This is an updated set of patches for Haswell enablement. I tried to address all the comments, and re-diffed the patches to simplify their inclusion into Daniel's tree. I have also split the PCI IDs definitions and their hook-up into the binding tables as well. But I think we should wait on picking up those 2 patches for now - the PCI ID allocation logic here will still receive some additional changes I think. Functionality-wise, those patches do detect digital outputs now, namely HDMI, but said outputs do not (yet) work. The digital output detection process is also different from what we had previously - we can detect the presence of a connection on a port via DDI port feedback, but we cannot say if it is HDMI or DP. So I am not quite certain on how to address this properly in the driver yet. For now, I just blindly assume that it is HDMI as I don't have any DP monitors or connectors to test :). But for all means, please consider that support for digital outputs in this series is still unfinished and will change considerable in the future. Nonetheless, any feedback on how to implement it properly is much welcome. Note that with the DDI buffers, the same port can drive DP and HDMI without any buffer configuration changes; and we can drive FDI and HDMI likewise. So I've split the DDI buffers settings into a separate patch to pre-configure the ports to their suggested connection settings at the init time, which should work for any combinations of outputs. As for other changes, there are some comments improvements, some register name changes, a new enum for DDI ports, some changes in SBI handchake handling, a couple of new clocks we need for digital outputs and a bit of changes in the DDI pipe settings handling code. So Daniel, as we talked on irc, could you check which of those patches could be early picked into your tree? This would reduce future patchbombs from my side - I'd expect to have at least a half-dozen new patches until we'll have working digital outputs in place..
